Re: Another remainer...
Juncker wasn't elected as President of the EU Commission (the EU has 5 (I think, I kinda lost count) presidents), he was appointed, in large part because Merkel thought he would make a useful puppet. His greatest democratic achievement was to become PM of Luxembourg, a mandate roughly equivalent to that of the Mayor of Croydon.
EU supporters often like to claim that the Commission is just the EU civil service, and the UK doesn't vote for the head of its civil service. But that's nonsense. From the EU’s own website, an admirably clear phrase, albeit hidden amongst a hell of a lot of obfuscation clearly intended to fool people into thinking that the EU Parliament is a legislature: "the European Commission, the only institution empowered to initiate legislation." Really not analogous to a civil service, then. If anything, more like the UK Cabinet.
